On to step 2:
The number 924 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 924

Going ahead to step 3:
When dividing 809 by 924, we get 0 with a remainder of 809.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 809, we get 809.
Include the next digit (7) from the dividend after 809, then repeat: 8097 / 924

Let's proceed to step 4:
The number 924 fits into 8097 8 times, leaving a remainder of 705.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 7392 from 8097, we get 705.
Grab the next digit (6) from the dividend, add it to 705, then carry on: 7056 / 924

Going ahead to step 5:
When dividing 7056 by 924, we get 7 with a remainder of 588.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Subtract 6468 from 7056 to get 588.
Include the next digit (4) from the dividend after 588, then repeat: 5884 / 924

Step 6:
5884 divided by 924 is 6 with a remainder of 340.
Write down 6 as next digit of the result. 
Result so far: 876.0
If we take 5544 away from 5884, we end up with 340.
Append the next digit (0) from the dividend to 340 and continue with: 3400 / 924

Let's proceed to step 7:
If we divide 3400 by 924, we get 3 and a remainder of 628.
Use 3 as the next digit of our solution. 
Result so far: 8763.0
Deduct 2772 from 3400 and we're left with 628.
Include the next digit (6) from the dividend after 628, then repeat: 6286 / 924

Advancing to step 8:
6286 divided by 924 is 6 with a remainder of 742.
Use 6 as the next digit of our solution. 
Result so far: 87636.0
If we take 5544 away from 6286, we end up with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Going ahead to step 9:
If we divide 7420 by 924, we get 8 and a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 87636.8
Deduct 7392 from 7420 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
The number 924 fits into 280 0 times, leaving a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 87636.8
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 11:
2800 divided by 924 is 3 with a remainder of 28.
The next digit of our result is 3. 
Result so far: 87636.803
The remainder is 28 after subtracting 2772 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
924 can be fit into 280 0 times, resulting in a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 87636.803
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 13:
924 goes into 2800 3 times with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 87636.80303
Subtracting 2772 from 2800 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
The number 924 fits into 280 0 times, leaving a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 87636.80303
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 15:
The number 924 fits into 2800 3 times, leaving a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 87636.8030303
Subtracting 2772 from 2800 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 16:
924 can be fit into 280 0 times, resulting in a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 87636.8030303
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

In conclusion, the division gives 87636.8030303 with a balance of 2.8e-07.
